ZEOflair 90 is a new, value-added adsorbent addition to the ZEOflair portfolio. ZEOflair 90 is strongly selective for the adsorption of a wide range of odors/VOCs from various packaging materials, even in high humidity conditions. It can effectively reduce a range of organic and inorganic compounds to imperceptible levels, despite the presence of water. Potential ZEOflair 90 applications for odor/VOC control include post-consumer (PC) and post-industrial (PI) and scrap/regrind polyethylene and polypropylene recycled streams. The best performance is achieved with PC/PI streams that either have low to no aromatic odor content or that have undergone prior odor pretreatment such as washing, or degassing, etc.
